Against the background of problems that the world economy is faced with Russia, he said, is obliged to take the necessary measures to maintain its economic development. "The situation that is taking shape in the international financial markets is a no simple one. There are problems with liquidity, but nevertheless we must do everything in our powers to ensure our economy should develop," Itar-Tass quoted Medvedev as saying at a conference at his country residence on Thursday. "Last year it demonstrated exceptionally decent development rates, probably, the best over years. You know yourself what the parameters are.
